Your mother recieved a robot vacuum cleaner as a gift and wants you to help her program it to clean a vacant 30 ft by 30 ft room. if the vacuum is at position (12,9) at time t=2 seconds and at position (24,18) at t=5 seconds. where did the robot start?

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
